Double slush edge

During warmer winter weather, snow and ice melt and form thick sheets of slush on the surface of the road. The slush wedge increases the balanced safety characteristics of the tyre in the rapidly changing Northern winter weather.

The slush wedges that improve the safety of the Nokian Hakkapeliitta 7 studded tyre on wet snow were originally developed for Central European non-studded winter tyres. They are commonly used in conditions where thawed snow is more common than in the north.

The slushplaning effect is doubled for the Nordic studded tyre: In the Nokian Hakkapeliitta 7, the slush wedge was added on both shoulders at the edge of the tyre. Its wedge-like angle effectively cuts through the wet slush between the road and tyre, thereby reducing the risk of slushplaning.
